Laravel-livewire：为什么触发事件会执行 render() 方法？

Question

This is the Livewire framework for Laravel

HTML:

<button wire:click="$emit('postAdded')">

PHP:

protected $listeners = ['postAdded' => 'showPostAddedMessage'];

public function showPostAddedMessage()
{
    // Do stuff
}

public function render()
{
    return view('livewire.index');
}

Clicking the button calls showPostAddedMessage() and after that render(). How can I listen for an event without calling render()?

Answer 1

I had the same issue. In my case, the render() method was closing my parent modal box. I just added "wire:ignore" in modal div. Livewire ignores that div whenever it calls the render() method

Answer 2

This is how livewire works. whenever you are changing anything / firing any event. the component will refresh. As far as I learned livewire, there is no way to stop it unless you are putting die() isnide showPOstAddedMessage function, which will be a very wierd way to solve it.

Answer 3

I've came to this sort of hack: if your concern is to not re-render the view, you can just return an empty string from render() . The DOM will not be updated.
My case: I've got a download method that is not supposed to render anything.

public function download()
{
   $this->skipRender();
}

public function render()
{
    if($this->shouldSkipRender) {
        return '';
    }
    
    return view("xxxxx");
}

As long as I'm not missing anything, this works for me.
